Description

Technical Field

[0001] This utility model relates to a ball valve structure in pipeline valves, specifically an integrated double-ball valve. Background Technology

[0002] In the installation and use of valves in heating network circulating water systems, especially in the return water pipeline, it is usually necessary to install independent shut-off valves, filter valves, and drain valves. Due to the different functions and structures of these valves, the installation process is cumbersome and complex, with numerous pipeline connection points. This not only increases installation and maintenance costs, but also commonly results in leaks due to poor sealing at valve connections, leading to resource waste and environmental pollution.

[0003] Existing technology includes a type of integrated double-ball valve that combines two ball valves into a single valve body. However, such valves are primarily designed to provide redundancy, meaning that if one ball valve fails to close effectively, the other ball valve can be activated to open or close the pipeline, thus preventing system shutdowns for maintenance. This design limits the double-ball valve to a single backup function, resulting in significant functional limitations.

[0004] Furthermore, these existing double-ball valves typically employ a standard stem and handle connection structure, lacking necessary safety protection measures. In actual operation, the valve's opening and closing status is easily manipulated or misoperated by unauthorized personnel, posing a significant threat to the safe and stable operation of the heating network system.

[0005] Meanwhile, since the aforementioned ball valves typically lack precise flow regulation functions or lack visual indicators during the regulation process, operators find it difficult to accurately control pipeline flow, which brings inconvenience to the system's refined regulation and energy management.

[0006] Therefore, there is an urgent need in this field for an integrated double-ball valve that combines multiple functions such as opening and closing, filtration, sewage discharge, anti-theft, and precise flow regulation, in order to fundamentally solve the above problems. Utility Model Content

[0007] The purpose of this utility model is to provide an integrated double-ball valve to solve the problems of single valve function, insufficient safety and inconvenient adjustment in the prior art. It integrates multiple functions such as opening and closing, filtering, sewage discharge, anti-theft and precise flow regulation.

[0008] The technical problem of this utility model is solved by the following technical solution: An integrated double-ball valve includes a valve body, a first ball valve, a second ball valve, and a filter assembly. The valve body is an integrally formed three-way valve body with an inlet, an outlet, and a drain port. The first ball valve is installed at the inlet, the second ball valve is installed at the outlet, and the filter assembly is installed at the drain port. A cavity is formed on the top of the valve body corresponding to the position of the first ball valve. The top end of the first valve stem of the first ball valve is housed in this cavity. The port of the cavity is closed by a removable magnetic locking cap, so that the top end of the first valve stem is closed in the cavity. The magnetic locking cap is magnetically coupled to an independent magnetic handle and can be installed or removed from the port of the cavity. After the magnetic locking cap is removed, the magnetic handle engages with the top end of the first valve stem to drive the first valve stem to rotate. A handle and an opening indicator assembly are installed on the top end of the second valve stem of the second ball valve.

[0009] The inlet and outlet are coaxially arranged; the centerline of the sewage outlet forms an acute angle with the centerline of the outlet.

[0010] The opening indicator assembly includes a dial fixed to the valve body and a pointer fixed to the handle or the second valve stem and cooperating with the dial.

[0011] The first valve core of the first ball valve is a ball valve core; the second valve core of the second ball valve is a V-shaped ball valve core.

[0012] The filter assembly includes a filter cylinder and an end cap; the filter cylinder is detachably housed in the drain port and sealed and fixed by the end cap; the end cap has a drain hole and a drain valve is installed at the drain hole.

[0013] The magnetic handle includes an operating lever, one end of which is provided with a magnetic head for magnetic coupling with the magnetic lock cap, and the other end is provided with a drive head for engaging with the top of the first valve stem to transmit torque.

[0014] The first valve stem is driven to rotate by a magnetic handle to control the opening and closing of the first ball valve; the second valve stem is controlled by the opening indicator component to control the rotation angle, thereby controlling the flow regulation of the second ball valve.

[0015] Compared with existing technologies, this utility model mainly integrates the valve body into a three-way valve body with an inlet, outlet, and drain port. A first ball valve is installed at the inlet, a second ball valve at the outlet, and a filter assembly at the drain port, thus achieving structural integration. Simultaneously, for safe opening and closing control, a cavity is formed at the top of the valve body corresponding to the position of the first ball valve. The top of the first valve stem of the first ball valve is housed within this cavity, and the port of the cavity is sealed by a detachable magnetic locking cap, thus enclosing the top of the first valve stem within the cavity. The magnetic locking cap and an independent magnetic handle can be magnetically coupled to be installed or removed from the port of the cavity. After removing the magnetic locking cap, the magnetic handle can engage with the top of the first valve stem to drive the first valve stem to rotate, thereby controlling the opening and closing of the first ball valve. This structure effectively provides anti-theft protection. Furthermore, to achieve precise flow regulation, a handle and an opening indicator assembly are installed at the top of the second valve stem of the second ball valve. The second valve stem can be rotated by the indication of the opening indicator assembly to control the flow regulation of the second ball valve. Therefore, through the cooperation of the above-mentioned integrated structure and proprietary control components, this utility model successfully integrates multiple functions such as opening and closing, filtering, sewage discharge, anti-theft, and precise flow regulation, effectively solving the problems of single valve function, insufficient security, and inconvenient adjustment in the prior art.

The same labels in each figure represent the same components.

[0022] An integrated double-ball valve, such as Figure 1 , Figure 2 As shown, it is mainly used in the circulating water system of the heating network. Its structure includes valve body 1, first ball valve 2, second ball valve 3 and filter assembly 4.

[0023] The valve body 1 is an integrally formed three-way valve body with an inlet 11, an outlet 12 and a drain port 13. The inlet 11 and the outlet 12 are coaxially arranged, that is, on the same horizontal axis. The axis of the drain port 13 forms an acute angle with the axis of the outlet 12, that is, the axis of the drain port 13 intersects with the line connecting the inlet and outlet.

[0024] The first ball valve 2 is installed at inlet 11, that is Figure 1 The left port of the view shown; the second ball valve 3 is installed at outlet 12, that is Figure 1 The view shown is the right port; the filter assembly 4 is installed at the drain outlet 13, which is... Figure 1 The port shown in the view below demonstrates that the above design enables structural integration.

[0025] The first ball valve 2 is a locking ball valve, and its first valve core 22 is a ball valve core, which is rotatably sealed in the inlet 11 by a threaded left end cap 6. The rotation axis of the first valve core 22 is exactly perpendicular to the axis of the inlet 11. The second ball valve 3 is a flow regulating ball valve, and its second valve core 32 is a V-shaped ball valve core, which is rotatably sealed in the outlet 12 by a threaded right end cap 7. The rotation axis of the second valve core 32 is exactly perpendicular to the axis of the outlet 12.

[0026] Meanwhile, in order to achieve safe opening and closing control, a cavity 23 is formed on the top of the valve body 1 corresponding to the position of the first ball valve 2, and the top end of the first valve stem 21 of the first ball valve 2 is housed in the cavity 23. The port of the cavity can be closed by a detachable magnetic locking cap 24, so that the top end of the first valve stem 21 can be closed in the cavity 23.

[0027] Then, the magnetic lock cap 24 is magnetically coupled to an independent magnetic handle 8 and is attached or detached from the port of the cavity 23. The magnetic handle 8 includes an operating rod 81, one end of which is provided with a magnetic head 82 for magnetic coupling with the magnetic lock cap 24, and the other end is provided with a drive head 83 for engaging with the top of the first valve stem 21 to transmit torque. This structure makes it necessary to use a dedicated magnetic handle 8 to operate the first ball valve 2, thereby achieving the anti-theft function.

[0028] In addition, to achieve precise flow regulation, a handle 33 and an opening indicator component 5 are installed at the top of the second valve stem 31 of the second ball valve 3. The opening indicator component includes a scale 51 fixed on the valve body 1 and a pointer 52 fixed on the handle 33 or the second valve stem 31 and forming an indication with the scale, so as to facilitate direct observation of the opening angle of the handle 33. In this way, the rotation angle of the second valve stem 31 can be driven by the indication of the opening indicator component 5, thereby controlling the flow regulation of the second ball valve 3, that is, the opening and flow of the second ball valve 3 can be linearly adjusted.

[0029] The filter assembly 4 includes a filter cylinder 41 and an end cap 42. The filter cylinder 41 is a cylindrical mesh cylinder that can be detachably housed in the drain port 13 and is sealed and fixed by the end cap 42 by threaded tightening. The end cap is also provided with a drain hole 421 and a drain valve 43 is installed at the drain hole to facilitate the discharge of sediment in the drain port 13.

[0030] Therefore, through the combination of the above-mentioned integrated structure and proprietary control components, this utility model successfully integrates multiple functions such as opening and closing, filtration, sewage discharge, anti-theft, and precise flow regulation, effectively solving the problems of single valve function, insufficient safety, and inconvenient adjustment in the prior art.

All technical solutions falling within the scope of this utility model's concept are within its protection scope. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within its protection scope.
